GILLET, OF OMAHA, NEBRASKA, ASSIGNOR TO JUBILEE MANUFACTURING00., OF OMAHA, NEBRASKA, A CORPORATION OF NEBRASKA WARNING SIGNALApplication filed January 15, 1932. Serial No. 586,737.

The present invention relates to warning signals and the like, and moreparticularly to a signal or sounding device adapted to be operated byfluid pressure, such as air.

The invention aims to provide a novel construction of sounding orwarning signal or device which may be connected to the intake manifoldof an internal combustion engine for operating the signal from thesuction in the intake manifold, and to provide an improved structure ofthe body part or bracket of the device which may be connected directly,or otherwise, with the intake manifold for operating the device.

Another object of the present invention is to provide a signal orsounding device of this character adapted to produce two or more tones,and to provide a controlling or valve means for the device by meansofwhich the tones may be simultaneously or'consecutively sounded so as toproduce the desired sounding or warning, such as to produce a high noteand a low note.

A further feature of the present invention is to provide a novelconstruction of sounding device or warning signal which may beconstructed so as to simulate the bray of a donkey which is commonlycalled heehaw, and a sounding device which by a selection or interchangeof the controlling valve may be made to simulate the trumpeting of anelephant; the device being adapted to be used in advertising politicaland other like campaigns.

The invention also provides an improved construction of bracket which isrelatively light, simple and of small size which provides a mainconnecting opening and a pair I of branch openings with means forsupporting horns or other fluid actuated sounding devices with respectto the branch openings, and which also embodies inits construction anovel valve casing for removably supporting a valve so that the valvemay be interchanged with other like valves having their communicatingports or openings disposed in various ways to effect different desiredresults.

With the foregoing and other objects in .view, the invention will bemore fully detions. of the high and low tone sounding dewarning signalconstructed according to the scribed hereinafter, and will bemoreparticu- '1 larly pointed out in the claims appended hereto. v

Referring now to the drawings, and first to Figure 3, 1O designates thebody of a motor vehicle providedwith a steering column 11 supporting thesteering wheel 12 at its upper, end, and 13 designates a hood-withinwhich is housed aninternal combustion engine'l l of any suitable typeand provided with an intake manifold 15.

'maybe of substantially Y -sh ape, as shown in Figures 1, 2 and 4, andwhich at its lower end is provided with an externally threaded mainsection 17 adapted to be tapped into the upper or other suitable portionof the manifold 15, as shown in Figure 3 so as to estab lishcommunication between the interior of the body bracket 16 and themanifold. The body bracket 16 is provided with a pair of upwardlydiverging branches 18 which communicate at their lower ends with themain stem or section 17 and which are'also externally threaded so as toreceive thereover the inner ends of horn casings 19. and 20 which aredetachably threaded or mounted upon the branches 18. The horns 19 and 20are preferably made of different sizes with one horn 19 relatively largeand the other horn 20 relatively small so that a low or deep tone may beproduced with the larger horn 19 and a higher pitched tone with thesmaller horn is fitted between the flanges 211and held inter-e mediatelyin the casin of the horn 19. The disc 22 is provided with a slot oraperture 23 at its intermediate portion which is closed by anoverlapping reed or leaf 2 1 secured at one end by rivets 25, or thelike, to the plate 22 for normally closing the opening 23. The leaf 24has suflicient inherent resiliency to 'normally lie flat against thelower side of the di c 22 and is adapted to flex under the suction fromthe manifold 15, and is proportioned to vibrate and thus produce arelatively low or deep tone.

. The smaller horn 20, as shown in Figures 4, 7 and 8, is provided withan intermediate disc 26 secured between the overturned and interlockingflanges 27 and the casing of the horn 20 in a manner similar to thatshown -at 21 in the larger horn, and the disc 26 is provided with arelatively small slot or opening 2.8 at its intermediate portion whichis normally closed by a flexible reed or plate 29 secured by rivets 30to the disc 26. As shown 5 in Figure 7 the reed 29 and the opening 28preferably taper toward the free end the reed 29 so that a relativelyhigh pitched sound or tone is provided by suction in the manifold 15.The branched body 16 is pro- I vided with a valve casing-31 asanintegral part of the bracket 16 and which comprises 18 may beindependently controlled by different valve structures mounted in thecasing 31. The valve casing 31 extends in the form of hollow bushings orsleeves at the front or rear edges of the body bracket 16, as shown inFigure 4C particularly.

Different types of valves may be mounted in the casing 31. In Figure 1 avalve 32 is shown. This valve is shown in detail in Figurell, andcomprises a cylindrical rod which may be solid, or otherwise, and ofsufficient length to extend entirely through the valve casing 31 andbeyond the inner end of the valve casing to support and expand thespring 33 which bears at one end against the forward end of the valvecasing 31 and at its other end against a pin 34: or other suitabledevice carriedonthe valve rod 32 for normally urging the valve rod 32forwardly in the casing. is provided with a' bail 35 or link to whichmay be attached a pull rod 36 of anysuitable construction and which isslidably mounted upon a bracket secured to the steering post .11in'suitable position beneath the steering wheel 12. The rod 36 may havea pull ring 38 to facilitate the engagement and pulling of the rod 36for retracting the valve 32 against thetension of the spring 33.-

The valve rod- 32 is provided with two apertures or openings .39 and 40each of which are of suitablelength and which are spaced apart adistance equal substantially to the The rear end of thev'alve rod 32distance between the brackets 18 at their,

points of intersection with the valve casing 31. The openings 39. and 40are thus relatively positioned, and relatively proportioned so that whenthe valve rod 32 is drawn backwardly both of the ports 39 and 40 open.

simultaneously and the suction in the mani fold 15 is communicatedsimultaneously to V the horns 19 and 20 and effect the dual simultaneoussounding of thedevice.

-Nojrmally the ring 38'holds the valve rodew 32in a forward position soas 'to dispose the solid'portions of the rod 32 in, register with thebranches 18 and thus cut off communica tion between the branches andthemanifold.

V A slight modification of the valve rod is shown in Figures 2 and 12.The valve rod 41 is provided with two passages or openings 12 and 43which are widelyspaced apart along the valve rod and which are solocated that, in the normal closed position of the valve, the opening 12lies between the branches 18 and the solid portions of the valve rod 41are in register with the branches so as to close communication betweenthe same and the manifold. The intermediate portion of the rod whichlies between the openings 42 and 43 isrelatively long so that as thevalve rod 41 is drawnbackwardly the opening 12 first registers with therear branch 18 while the forward branch is still maintained closed. Theintermediate portion of the valve rod 41 must pass rearwardly of theforward branch and consequently cut ofi both branches so as to silencethe device prior to the registering ofthe opening 43 with the forwardbranch ofthe device. Thus, one of the horns such as the horn 20 is firstsounded. There is then a period of silence during the further backwardmovement of the valve 41, and finally the larger horn 19 is sounded. Thereeds 24 and 29 of the horns may of course be modified or changedorsubstituted by other suitable operating mechanisms to produce desiredtones or noises when the valve is operated.

Figures 4 and 9 show another slight modification of the valve rod 44wherein the valve rod is providedwith openings 45, 46 and 47.

The rear opening or port 45 of the valve rod.

is near the bail or link 35 so that upon the first movement of the valverod 44 the horn 20 is operated, and upon the further movement of thevalve rod 44 the warning is silenced and then the larger horn 19 isgiven two separate and distinct blasts with a short intermissiontherebetween. It is of course understood that these openings or ports inthe various valve rods may be of any desired number and spaced along thevalve rods in any desired manner so as to efiect the desired sounding ofthe horns 19 and 20.

As shown in dotted lines in Figure 1, the horns 19 and 20 may beinterchanged so that by the use of the same valve rod or rods anopposite effect may be obtained.

If a valve stem is employed, such as shown at 41 in Figures 2 and 12 ahee-haw sound will be produced by moving the valve rod 41 rearwardlyuntil the annular notch or port 42 permits communication between therear branch 18 and the main stem 17 of the valve casing, sounding thesmall horn 20 and producing a tone simulating the hee. Further rearwardmovement of the valve rod 41 cuts off the above described communicationbetween the rear branch 18 and the manifold, and brings the annularnotch or port 43 into register with the forward stem 18 to establishcommunication between the same and the manifold 15, and operating thehorn 19 to produce the proper or deeper tone haw, completing the desiredsignal or sound.

In each instance the spring 33 returns the valve rod to normally closedposition when the rod 36 is released. In the same manner, the horns maybe proportioned or modified to simulate the trumpheting of an elephantor any other desired sounds or combinations thereof, within the limitsof the structure.
